National Academies issues final Hanford LAW report
The National Academies of Sciences, Engineering, and Medicine on February 21 released its fourth and final report on its review of possible approaches to treating low-activity waste at the Hanford Site. The Department of Energy plans to vitrify approximately 56 million gallons of radioactive and chemical waste at the Waste Treatment and Immobilization Plant, which is currently under construction at Hanford. The waste will be separated into high-level waste and low-activity waste (LAW) streams before being turned into a solid glass form through vitrification. Not all of the LAW, however, will be vitrified, and the DOE has not determined a treatment method for the excess waste, called supplemental LAW (SLAW).
